Structural configuration and phase stability in full Heusler alloys Cr2ZnSi and Cr2ZnGe

First Principles calculation of Half metallic proprieties of QCrAs (Q=Hf, Ti and Zr)

“…Of all materials that have been found and synthesized till date, the Heusler alloys and its family have been one of the most widely studied material [5][6][7], this is because they can be easily synthesized and have multifunctional capability which are very useful in technological industries. The Heusler family with this multifunctional capabilities include the full Heusler alloy [8], quaternary Heusler alloy [9], half Heusler alloy [10], binary Heusler alloy [11], and inverse Heusler alloy [12]. Interestingly, different characteristics of these Heusler family can be predicted just by knowing their valence electron count [13].…”

Electronic structures, magnetic properties, and martensitic transformation in all-d-metal Heusler-like alloys Cd2MnTM (TM = Fe, Ni, Cu)*

“…[20,21] The metamagnetic MTs and corresponding multifunctional properties (magneticentropy change, [20] field-induced strain, [21] giant elastocaloric effect [11,22,23] ) were gained in MnNiTi(Co) system. Wei [22] reported a reversible elastocaloric effect with ∆T ad = 9.0 K at a strain level of 4.6% for Ni 35 Co 15 Mn 35 Ti 15 . Aznar [23] reported a giant barocaloric effect for Ni 50 Mn 31.5 Ti 18.5 , which has maximum value of adiabatic temperature (12 K) and isothermal entropy changes (74 J•kg −1 •K −1 ) under 4 kbar (1 bar = 10 5 Pa).…”

“…Recently, Han et al [34] found that the Zn 2 MnT M crystalize L2 1 -type structure with ferromagnetic state, Zn 2 RuMn, Zn 2 RhMn, Zn 2 OsMn, and Zn 2 IrMn have possible MT. Yang et al [35] reported the atomic configura-tions, electronic, magnetic, mechanical, and dynamic properties for Cr 2 ZnSi/Cr 2 ZnGe.…”

Structural configuration and tetragonal phase stability in the equiatomic quaternary Heusler compound TiZnMnSi

“…The family of Heusler materials stand out as one of the most promising candidates due to their excellent electronic and magnetic characteristics, such as, high Curie temperature, compatible crystal structure and tuneable properties. Initially, Heusler compounds have two typical classes: [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] half-Heusler with generic chemical formula XYZ and full-Heusler with formula X 2 YZ, where X and Y represent the transition metal elements and Z is from the main group elements. Despite the different stoichiometric ratios in these two Heusler kinds, there are always three elements in both of them and thus they can be regarded as ternary compounds.…”
